SPECIFICATION forming part of Letters Patent No. 265,363, dated October3, 1882.

Application filed Maylflz, 1882.

To all whom it may concern:

Be it known that I, EDGAR W. ANTHONY, of Boston, in the county ofSuffolk and State of Massachusetts, a citizen of the United States, haveinvented a certain new and useful Improvementin Heating-Stoves, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying d rawings, forming a part of this specification,in explaining its nature, in which- Figure 1 is a perspective view ofastove containing my invention. Fig. 2 is a vertical central sectionthereof from side to side. Fig. 3 is a vertical central section thereoffrom front to rear. Fig. at is a horizontal section on the dotted lineas a of Fig. 2, and Fig. 5 is a horizontal section on the dotted line yy of Fig. 2. Fig. 6 represents a portion of one side and of the rearendofthe stove, in perspective, to better illustrate the construction. Fig.7 is a vertical section upon the line 2 z of Fig. 4:. Fig. Sis aperspective of a part of one side, representing a constructionhereinafter described; and Fig. 9 shows in enlarged perspective andsection the cover to the magazine. Fig. 10 is a perspective view of theinner side of the stovepanel, hereinafter described. Fig. 11 is a viewrepresenting a modification in construction, hereinafter described.

The invention relates to the class of stoves known as low-magazine orbase-burning stoves; and it comprises a novel arrangement of the finesand air-heating chamber, means for supplying the combustion-chamber withair from the air-heating chamber, means for making the magazineair-tight, the construction, hereinafter specified, whereby the gratemay be shaken from the side of the stove, the manner of attaching to thestove a swinging panel ordoor, themannerofattaching thecover of themagazine to the stove, and various other features.

In the drawings, A is the ash-pit; B, the

heating-chamber is separated from the ash-pit" by the vertical plates ata, forming the sides of (No model.)

the ash-pit, and by the horizontal plate a forming its bottom, and theplates are also, in connection with the rear plate, a and front plate,a, form the Walls of the fire-pot, to which the tire-brick a is alining. The air-heating chamber F is surrounded upon its bottom andsides by the tines G G G the flue G being upon one side and the flue Gupon the other side of the stove, and both flues beingthe downpassagesfrom the combustion -chamber D. They unite under the chamber F, formingthe flue G The flue-plates g g 9 direct the products of combustion intheir passage from the tines G G into the flue G so that the heat andproducts of combustion from both flues, instead of coming directly incontact, are turned in the same direction and have the same generalcourse where they meet from the flue G. They enter the uptake G at therear of the stove. The flue-plates g g g are formed, substantially asshown in Fig. 5, to provideihe openings f from underneath the stove intothe horizontal portion of the chamber F. The plate separates the loweror base flue, G from the heating-chamber, and the side plates, g, theside portions of said chamber F from the downflues G G.

G are the outer side plates of the stove.

Arranged over the heating-chamber F at the sides and at the rear, ifdesired, is the small chamber H, which is formed by means of the curvedplate h. and the curved upper portion of the side plates, g. This curvedplate It may be separate or cast with the plates a a, and it has theperforations h on its upper portion, whereby the chamber is connectedwith the combustionchamber, and the plates 9 also have holes whereby thesaid chamber H is connected with the heating-chamber F. Thisconstruction provides air for assisting combustion in thecombustion-chamber and in what is called a gas-burner. It varies fromothers in that the supply of air is taken from the airheatingchamber.The heating-chamberF has openingsf at .the frontof the st0ve,f at therear for the escape of the heated air from its side portions, andsuitable openings for the same purpose in the rear portion.

in order that the grate may be shaken from the side of the stove, Ihaveattached the panel K to the stove so that it may be swung to one sideand provide an opening to the chamber F, and there is formed by the walla a box or inclosnre, it, into which the end of the shaft or shafts forturning the'grate projects, and which box projects into the chamber F,as shown in Fig. 8. A swinging slide or door, it, serves to close thefront or end of the box. Q

\Vhen it is desired that the panel shall appear to be stationary and notto be a door closing an opening I use the construction herein described,or one substantially like it, consisting of the link is, pivoted to thelug or projection 7; upon the inside of the panel and at L to the frameof the stove within the chamber F, and the latch 7.1 which is adapted toengage with the catch It. This method of supporting the panel does notappear from the outside of the stove and does not interfere with itsornamentation.

The cover 0 of the magazine consists of the plate 0, preferably having adownwardly-extending flange, 0 and I may use in connection therewith thepacking c, which is held to the plate 0 by the retaining-plate e, whichis bolted or otherwise fastened to the upper plate. This packing may beof asbestus board, or of vulcanized compound, like the Jenkins packing,orof any othersuitablematerial, and when the packing is employed Iprefer to form the supporting-ledge c with the raised seat a, up onwhich the packing shall rest when the cover is in position, the flange eshutting beyond the raised seat and not upon it, and not extending tothe horizontal portion of the supporting-ledge 0", so that the entireweight of the cover is upon the raised seat, thereby bringing the raisedseat and packing in close contact. As the weight of the cover may not,however, always be sutiicient to force the packinginto contact with themetal seat, I have represented independent means for pressing the coverto its seat, consisting of the link c", to which the cover is pivoted at0 and which is in turn pivoted to theframe of the stove at e, and thelocking-bar c which is pivoted to the plate 0, and is adapted to beswnngnnder the ledge or projection c and wedge the cover 0 to its seat.Over this magazine-cover is arranged another cover, 0, which is hingedto the top plate of the stove, and is adapted to be operated in theordinary manner.

The grate which I prefer to use with this stove is that known as theCard grate, and is described in Patent No.220,46-t, October let, 1575).

The back plate, a, is provided with an extension, 0, forming a box, 0,which is at the rear of the ash-pit chamber, and which opens into thedirect uptake G by means of the holes (Fill the plate 0. This,as isobvions,isa dusti'lne for the escape of dust form the ash-pit when thegrate is being shaken or ashes removed; and I use a perforated plate toprevent ashes from falling into the uptake. Be-

hind the plate 0 is a damper, 0, also perforated to correspond with theperforations in the plate 0, and which damper is adapted to be moved toclose or open said passages 0 It will be observed that the side portionsof the chamber F are so shaped that they divide the verticalflnes G Ginto two parts-one part at the front corner of each side and the otherat the rear corner of each side. By thus dividing the flue into twoparts I obtain a much more uniform passage of heat through the tlnesthan would be the case if the tines were not thus separated into twopassages, for if they were not separated the tendency of the heat andproducts ofcombnstion in passing through the fines would be to take thecourse toward the front corner of the stove, as that would be theshortest passage from the combustionchamber to the uptake; but bydividing the fines as indicated the effect is as I. have described, theheat and products of combustion being divided into two very nearlyuniform currents or streams.

That portion of the invention which is herein illustrated as applied tothe cover 0 of the magazine-namely, the providing ofa packing for moreeffectually sealing the joint of the door-array of course be used forany other stove door or joint without departing from the spirit of theinvention, and of course it may be used therein, if desired, with meansfor forcing the door or section to its seat, to provide a proper andclose contact between the packing and the part of the stove againstwhich it is brought in contact; and in lieu of the constructiondescribed for forcing the cover to its seat I may useascrew which shallpass through a proper support. \Vhen this construction is used the coverc should be fastened at its front to the stove-frame by a button or inany other suitable way, and the screw passed through a nut therein andbear with its lower cud upon the cover 0, whereby upon turning the screwthe cover may be forced to its seat.

It is not necessary that the packing be in a sheet, for it may be cut instrips and of a width sufficient to cover or partially cover the raisedseat,and be held in place by a binding or clamping plate.

The magazine is preferably rectangular in cross-section, and is withoutmeans for cnlarging its discharge'opening, which is made of a propersize in the tirst instance and needs no further regulation.

It is not necessary for the purpose of the invention that the portion ofthe heatingchamher at the rear of the stove between the up take and therear plate, a, be used; neither is it necessarythat the air-heatingchamber la be between the lines G G and the ash-pit and fire-pot, asthey may be upon the outside of the tlues without departing from thespirit of the invention.

It will be observed, also, that the tine-plates g may be cast with thebase-plate of the stove, and that they perform two 0liices namely, thatof directing the passage of the products of combustion through the finesand that of providing a passage for the entrance of the cold air to beheated to the heatingchamber.

In lieu of perforating the plate 0 and arranging the perforations in thedamper 0 to correspond, I may make large apertures in the plate 0.(shown in Fig. 11,) and may arrange the perforations in the damper 0 sothat they may be brought in line with the apertures in opening the flue,and may be moved behind the solid portion of the plate in closing thefluethat is, the construction would be like an ordinary front draft of astove, with the exception that in lieu of having apertures in the damperto correspond with the apertures in the plate the damper is made of onepiece of metal and provided with perforations.

In addition to the outletsff for the escape of heated air from theheating-chamber I may provideoutletsf about the panel K K. Theseescape-openiugs or apertures are provided by forming the recesses in thehorizontal portions or edges of the panels preferably upon the sides andtop, and a perspective of a panel shaped in this manner is representedin Fig. 10.

The stove-pipe collar 11 is supported by the movable plate 1), which isheld to the frame of the stove by screws p or in any other suitable way,the collar preferably being nearer one end of the plate than the other,so that by reversing the plate provision for adjustment to two heightsor levels is obtained. Below the plate 1) is another plate, 19 which isremovable from the back of the stoveand interchangeable with the platebearing the collar, so that by removing the plate nearing the collarfrom the position that it is in to that occupied by the lower platestill further provision for adjustment as to height of the collar isobtained,

in which event of course the lower plate will take the place of the onebearing the collar.
